Finally got the old cam pulled out last night, was showing some wear on the lobes so im glad i pulled it but upon measuring lobes they are exactly the same as the 6.4 cam #5045517ac used in the 2500's. Pretty disappointed. Different #'s stamped in back side also the ID grooves are differnent at the back bearing. Makes no sense to me as i found that the 5.7 eagle vvt specs call for lobe lifts at around .498? Duration might be different, i could not tell? I guess it is a good find if same or better the the stock 2009-2018 camshaft as it is way cheaper. I am hopeing to have truck up and running friday night.
